Biodiversity Data Journal 4: e9042. doi: 10.3897/BDJ.4.e9042 Abstract Background The checklist of British and Irish Ichneumonidae is revised, based in large part on the collections of the Natural History Museum, London and the National Museums of Scotland, Edinburgh. Distribution records are provided at the country level. New information Of the 2,447 species regarded as valid and certainly identified, 214 are here recorded for the first time from the British Isles. Neorhacodinae is considered to be a separate subfamily rather than a synonym of Tersilochinae. Echthrini is treated as a junior synonym of the tribe Cryptini, not Hemigastrini. Echthrus Gravenhorst and Helcostizus Förster are classified in Cryptini rather than, respectively, Hemigastrini and Phygadeuontini. Keywords Britain, Ireland, fauna, Ichneumonoidea © Broad G.

Given the size of each family in Britain (over 1,300 braconids and nearly 2,500 ichneumonids) we are publishing the two checklists separately. This is one part of a series of papers revising the British and Irish list of Hymenoptera, that started with Broad (2014), Broad and Livermore (2014b), Broad and Livermore (2014a) and Liston et al. (2014). For the background and rationale behind these British Hymenoptera checklists see Broad (2014). The bases for the ichneumonid taxonomy are Yu and Horstmann (1997) and Taxapad (Yu et al. 2012) (ichneumonid data for both compiled by Klaus Horstmann). I have not relied on Yu et al. (2012) for data on species occurrence in Britain. Rather, I have relied mostly on the primary literature and collections, especially NMS and BMNH. Indeed, large parts of the checklist rely on original work, identifying specimens in these collections. The collections of the NMS have been invaluable in updating this checklist as Mark Shaw has very actively encouraged taxonomists to use the collections, which contain a large amount of recently collected, often reared, material. The late J.F. Perkins also did a huge amount to improve the BMNH collection of Ichneumonidae that was not really reflected in his published output. I have made great use of Perkins’s identifications as well as Horstmann’s, Andrey Khalaim’s and many other workers, including my own. Many Irish records are taken from O'Connor et al. (2007). All additions to and deletions from the British list since Fitton (1978) are recorded as well as country-level distribution within the British Isles (but regarding the Republic of Ireland and Northern Ireland as one geographical unit), i.e. England, Scotland, Wales, Ireland, Isle of Man. The current numbers of valid, certainly identified ichneumonid species are listed per subfamily and by country in Table 1. This highlights the lack of data from countries other than England. Because the ichneumonid literature is extensive and scattered I also provide many taxonomic references. Some changes to classification are employed here, following molecular phylogenetic studies (Laurenne et al. 2006, Quicke et al. 2009). Two genera that are usually classified in Hemigastrini and Phygadeuontini - Echthrus Gravenhorst and Helcostizus Förster - are transferred to Cryptini (as originally suggested by Laurenne et al. 2006), which means that Echthrini Narayanan & Lal, 1958, becomes a junior synonym of Cryptini Kirby, 1837. And, contrary to Quicke et al. (2009), Neorhacodinae is again regarded as a valid subfamily, not as a synonym of Tersilochinae, following phylogenetic work by A.M.R. Bennett et al. (in prep.) and reflecting differences in host use. Table 1. Numbers of confirmed British and Irish Ichneumonidae broken down by subfamily and country.

A handbook to the British fauna (Broad, Shaw & Fitton, in prep.) provides an introduction to the biology, classification and identification of this family of parasitoid wasps and will be published soon. 4 Broad G a b c d Figure 1.

I provide rather extensive Palaearctic synonymy and citations because if you do not have access to the Taxapad database (Yu et al. 2012) it can be very difficult to trace the fate of names in the voluminous and scattered literature, although some of the functionality of the catalogue is available online.

First, the species has been carried over from the previous checklist (Fitton 1978) and, although I have not seen any British specimens I have no reason to doubt the original identification. Second, specimens in collections are labelled with imprecise locality data, such as 'Great Britain'. This is the case with many of the older collections. 8 Broad G a b c d Figure 5.
